我试图在golang和lambda中创建子段，但它不适合我：
这是我的代码：

package main

import (
    "context"
    "fmt"

    "github.com/aws/aws-lambda-go/lambda"
    "github.com/aws/aws-xray-sdk-go/xray"
)

func handler(ctx context.Context, event int) (string, error) {

    awsContext, segment := xray.BeginSegment(ctx, "service-A")

    segment.Close(nil)

    sumResult, err := performSum(awsContext, event, event)
    if err != nil {
        return "", err
    }

    return fmt.Sprintf("Resultado: %d", sumResult), nil
}

func performSum(ctx context.Context, num1 int, num2 int) (int, error) {

    _, subSeg := xray.BeginSubsegment(ctx, "service-B")
    myMap := make(map[string]interface{})
    myMap["test"] = "test value"
    subSeg.Annotations = myMap
    defer subSeg.Close(nil)

    return num1 + num2, nil
}

func main() {

    lambda.Start(handler)
}

段被创建但子段没有，y尝试使用xRay。捕获和我有相同的结果。
在我的X射线控制台中：
（Client）->（My lambda Lambda Context）->（My lambda Lambda Function）
（客户端）->（服务-A）
我不知道为什么我的父段不是我的lambda，是其他客户端，我不知道为什么我的子段没有出现。
我已经阅读了所有的AWS帖子，所有的人都这样做，但我不明白我的基本示例发生了什么。
这是使用Capture的代码，但只有在控制台中才会出现Segment：
（Client）->（My lambda Lambda Context）->（My lambda Lambda Function）
（客户端）->（测试）
我以SDK测试为例：
https://github.com/aws/aws-xray-sdk-go/blob/master/xray/capture_test.go
但它不起作用！

func handler(ctx context.Context, event int) (string, error) {

    logger.InitAppContext(&ctx)

    ctx, root := xray.BeginSegment(ctx, "Test")
    err := xray.Capture(ctx, "TestService", func(context.Context) error {

        logger.Info(ctx, "Inside Capture")
        time.Sleep(2 * time.Second)

        root.Close(nil)
        return nil
    })

    return fmt.Sprintf("Resultado: %d", 0), err
}

func main() {

    lambda.Start(handler)
}

我做的另一件事是用xray创建一个HTTP请求，因为使用HTTP请求xray自动创建子段，它可以工作，然后在SDK库中我包括一些日志
这是带有Http请求的Json段（它工作，子段出现在控制台中）：

因为在埃尔塞贡多没有父母的身份，他也不会有什么影响
